Question

Two events, A and B, are independent of each other. P(A)=– and P(A and B)

Round to the nearest hundredth, if necessary.
What is P(B) written as a decimal?
A: 0.02
B: 0.04
C: 0.29
D: 0.75

Answer 1

D) 0.75

Explanation:

have a good day!

Answer 2

D: 0.75

`P(B) = (6)/(8) = 0.75`

Explanation:

Explanation:-

Independent events:

If the occurrence of the event 'B' is not effected by the occurrence or non- occurrence of the event 'A' then the event 'B' is said to be independent of 'A'

or

The two events are independent if the incidence of one event is not affect the probability of other event.

P(A∩B) = P(A) P(B)

Given data A and B are independent events

Given data

`P(AnB) = (1)/(8) and P(A) =(1)/(6)`

we know that A and B are independent events are

P(A∩B) = P(A) P(B)

`(1)/(8) = (1)/(6) P(B)`

Now calculation we get

`P(B) = (6)/(8) = 0.75`

Final answer:-

`P(B) = (6)/(8) = 0.75`
